TopTank 500L Cylindrical Water Tank, UV-Stabilized Polyethylene

TopTank 500L Cylindrical Tank

The TopTank 500L Water Tank serves as a reliable, mid-capacity storage solution for potable water in residential, commercial, and construction site environments. Manufactured from high-quality, food-grade polyethylene, this vertical vessel ensures safe liquid containment without the risk of leaching or contamination. Its cylindrical geometry optimizes structural integrity while maintaining a compact footprint for tight installation areas.

Built for the Job

Plumbers and site supervisors specify this container for its durability and ease of integration into existing pressurized or gravity-fed systems. The rotational molding process creates a seamless body, eliminating weak points often found in welded alternatives. This construction method prevents leaks under the hydrostatic pressure exerted by 500 liters of liquid. Contractors frequently deploy these units as header tanks or secondary storage in rainwater harvesting setups.

• Domestic backup storage for small households or apartments requiring consistent supply.

• Construction site water stations for mixing mortar, cleaning tools, or dust suppression.

• Header tank applications for solar water heating systems and gravity-fed lines.

Product Highlights

The outer layer features carbon black additives to block ultraviolet radiation and prevent algae growth inside the reservoir.

Food-Grade Material

• Manufactured from 100% virgin LLDPE for chemical inertness
• Certified safe for the storage of drinking water according to international standards

Technical Specifications

What’s Included

• 1 x 500L Cylindrical Storage Vessel

• 1 x Heavy-duty Threaded Inspection Lid

On-Site & Workshop Notes

• Ensure the installation surface is a level, smooth concrete plinth to prevent stress fractures in the base.

• Use flexible connectors when piping to the outlet to accommodate slight expansion and contraction of the plastic.

• Standard PVC or PPR tank connectors are compatible with the pre-marked inlet and outlet points.

• Keep the lid tightly secured to prevent debris ingress and maintain water hygiene in outdoor environments.
